I have a 1966 alpine. I just got it Thursday 9-23-21. The top was up. I had a heck of a time getting the latches open to get the top down. I finally got it. Later that evening I was putting it up. And it would not latch. I lack 3/4 to1/4 inch meeting the top of wind screen. HELP, what an I doing wrong or what do I need to do.
